Answer:

520 feets

Step-by-step explanation:

The height of the building, h can be obtuined using trigonometry ;

From the attached diagram, opposite side = 300 feets ; height, h = adjacent side

Hence,

Tan θ = opposite / Adjacent

Tan 30° = 300 / height

0.5773502 = 300 / height

Height = 300 / 0.5773502

Height = 519.615

Height = 520 feets

A submarine is cruising 8 meters below the surface. The captain orders a dive of another 17 meters. What is the new cruising dep
swat32

Answer:

25 meters.

Step-by-step explanation:

Given in the question that,

Initial depth of the submarine = 8 meters

After the order of the captain, the submarine was made to dive another 17 meters.

So, the final cruising depth of the submarine can be calculated by <u>adding the initial depth of the submarine and the depth further increased upon the order of the captain</u>.

Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.
